Drilling, bending, blanking, drawing, unscrewing, spinning and molding are all phases of the sheet metal forming and Earth Moving Fabrication process. They are especially suitable for hard and resistant metals such as iron and steel. Metal stamping is a widely used production process. It can be argued that this is one of the most important technologies in the manufacturing industry.
To continue to enjoy this status, the metal molding process must continue to be innovative and evolve continuously. The innovations in the production of sheet metal forming are aimed at reducing the times of the long and complex molding processes, maintaining the highest standards required by the various sectors of application.
Many industries use metal stamping machines for sheet metal processing. To be competitive, manufacturers in the sector must be able to expand their production capacity and also be more flexible. This is only possible when proper attention is paid to the details of the molding process as well as to the equipment and production tools.

How does the metal stamping process work?
In the sheet metal stamping process (also known as pressing), the material is perforated (or cut and preformed) using a molding press to make components in the desired shape and size.
The basic sheet metal pressing process consists of three main parts that will intervene in the operation of the machine: the sheet metal as a production material, the molding press and the molding die. Due to the fact that heat is generated by the friction during the manufacturing process, the printed parts are often very hot when they come out of the matrix.
Using Quick Die Change systems allows you to earn and maintain competitiveness in a sector, that of molding, which poses great challenges. The inclusion of a QDC program is generally the result of the transition to a so-called lean production method, known as the Just-In-Time (JIT) manufacturing system. The JIT system consists of producing exactly the right amount at the precise moment in which it is needed.
A streamlined, well-functioning production process eliminates redundant stocks. With a JIT production, the ideal size of a batch is a unique piece.
The bending in the air is carried out by means of an upper punch which, by descending, presses the sheet into a matrix lower than V. During this process the sheet has three points of contact with the machine: one on the upper punch and two on the matrix, determining the bend angle is the depth at which the punch presses the sheet in the matrix.
